PROCESSING APPARATUS, TRACE UNIT AND DIAGNOSTIC APPARATUS |
摘要 |
A processing circuit is responsive to at least one conditional instruction to perform a conditional operation in dependence on a current value of a subset of at least one condition flag. A trace circuit is provided for generating trace data elements indicative of operations performed by the processing circuit. When the processing circuit 4 processes at least one selected instruction, then the trace circuit generates a trace data element including a traced condition value indicating at least the subset of condition flags required to determine the outcome of the conditional instruction. A corresponding diagnostic apparatus uses the traced condition value to determine a processing outcome of the at least one conditional instruction. |
